Customizing the Toolbar for a List
To customize the toolbar for a list, you need to make changes to the Toolbar element within the SCHEMA.XML file for the list. To add a new link to the toolbar, for example, you can copy an existing definition for a link and then modify it. This maintains the nesting of tables that is used for displaying links and ensures that the appearance of the link you add is consistent with the other links.
Warning It is required that you create a custom site definition by copying an existing site definition, rather than modifying the original SCHEMA.XML file installed with Windows SharePoint Services. Changes that you make to the originally installed file may be overwritten when you install updates or service packs for Windows SharePoint Services, or when you upgrade an installation to the next product version. For information on creating a custom site definition, see Creating a Site Definition from an Existing Definition.
The following example adds a link on the toolbar of a list to a document that is contained in the Shared Documents folder.
<tr><td style="padding-left: 2px;padding-bottom: 2px" width=100%>
<table border=0 cellpadding=0 cellspacing=0 width=100%>
<tr><td width=100% class="ms-unselectednav" colspan=2>
<table cellpadding=0 cellspacing=0 border=0><tr><td valign=top>
<img src="../../_layouts/images/rect.gif"> </td>
<td><A HREF="]]></HTML><HttpVDir/>
<HTML><![CDATA[/Shared Documents/MeetingNotes.doc">]]></HTML>
<HTML>Type Conversions</HTML><HTML><![CDATA[</A></td></tr></table>
</td></tr></table>
</td></tr>
The example shows the toolbar link nested within three tables. The two tables in the example are contained within opening and closing TR and TD elements that belong to a third table which serves as the frame for containing all the links in the toolbar.
The HttpVDir element, which returns the root directory of the current subsite, is used to construct the complete path for the URL.
When a new list is created based on this template, a link to a MeetingNotes.doc file appears in the toolbar.
